inside the Linux kernel, the following vulnerability has become solved: mtd: parsers: qcom: take care of lacking totally free for pparts in cleanup Mtdpart doesn't free pparts each time a cleanup purpose is declared. insert lacking free of charge for pparts in cleanup purpose for smem to repair the leak.
from the Linux kernel, the next vulnerability continues to be solved: vsock: get rid of vsock from linked desk when join is interrupted by a signal vsock_connect() expects that the socket could already be from the TCP_ESTABLISHED state once the connecting activity wakes up with a sign pending. If this transpires the socket might be from the connected table, and It's not necessarily eliminated once the socket condition is reset. In this example It's normal to the process to retry hook up(), and When the link is profitable the socket will be extra to your related desk a 2nd time, corrupting the record.

It uses "page_mapcount(web site)" to come to a decision if a COW website page ought to be NUMA-safeguarded or not, and which makes Certainly no sense. the quantity of mappings a web site has is irrelevant: not just does GUP get a reference to some page as in Oded's circumstance, but one other mappings migth be paged out and the only reference to them would be in the web page count. Since we should always never seek to NUMA-equilibrium a page that we will not shift anyway resulting from other references, just take care of the code to implement 'page_count()'. Oded confirms that that fixes his problem. Now, this does indicate that some thing in NUMA balancing winds up switching web page protections (besides the obvious among making the site inaccessible to get the NUMA faulting data). usually the COW simplification wouldn't make any difference - considering that carrying out the GUP to the webpage would make sure It truly is writable. the reason for that permission modify can be good to determine far too, as it Evidently ends in spurious COW gatherings - but repairing the nonsensical take a look at that just transpired to work prior to is clearly the CorrectThing(tm) to perform Irrespective.
since the 'is_tx = 0' cannot be moved in the entire handler on account of a achievable race concerning the delay in switching to STATE_RX_AACK_ON as well as a new interrupt, we introduce an intermediate 'was_tx' boolean only for this goal. there is not any Fixes tag implementing right here, quite a few improvements have already been designed on this spot and The difficulty sort of constantly existed.
while in the Linux kernel, the next vulnerability has been fixed: mm: don't endeavor to NUMA-migrate COW web pages that produce other utilizes Oded Gabbay reports that enabling NUMA balancing triggers corruption with his Gaudi accelerator exam load: "All the main points are within the bug, but The underside line is usually that somehow, this patch leads to corruption in the event the numa balancing aspect is enabled AND we do not use process affinity AND we use GUP to pin internet pages so our accelerator can DMA to/from procedure memory. possibly disabling numa balancing, utilizing process affinity to bind to certain numa-node or reverting this patch leads to the bug to disappear" and Oded bisected the issue to commit 09854ba94c6a ("mm: do_wp_page() simplification"). Now, the NUMA balancing should not essentially be modifying the writability of a website page, and as such should not make a difference for COW. but it surely seems it does. Suspicious. nevertheless, in spite of that, the situation for enabling NUMA faults in change_pte_range() is nonsensical.
An publicity of delicate details vulnerability in GitHub organization Server would allow an attacker to enumerate the names of personal repositories that utilize deploy keys. This vulnerability didn't let unauthorized access to any repository written content Aside from the name.

- A packet SKB might be made whose tail is way beyond its conclude, producing out-of-bounds heap knowledge to become viewed as Section of the SKB's data. I've examined that this can be used by a malicious USB unit to send a bogus ICMPv6 Echo Request and obtain an ICMPv6 Echo Reply in response that contains random kernel heap data. It really is probably also achievable for getting OOB writes from this on a little bit-endian system somehow - perhaps by triggering skb_cow() by way of IP solutions processing -, but I haven't analyzed that.

So the same procedure should be applied to all DSA switch motorists, and that is: possibly use devres for both equally the mdiobus allocation and registration, or don't use devres in the least. The gswip driver has the code construction in spot for orderly mdiobus elimination, so just swap devm_mdiobus_alloc() with the non-devres variant, and insert guide free exactly where vital, making sure that we don't let devres cost-free a however-registered bus.
